McLaren SLR

Though the trend is to go green, we don’t think the horsepower war is over. For that reason we bring you the new RENNTECH 777, a Mercedes-McLaren SLR based beast that outputs nothing more and nothing less than 777 bhp from a highly tweaked 5.5-liter supercharged Kompressor V8 engine. With an aero-kit that packs big wings, splitters and skirts, new suspension, a stronger transmission and a limited-slip differential, the little monster is expected to top at 210 mph. We’re sold on the design, but to be honest we’d expect a much better performance from such an engine. No? [via WCF]

Some lucky and smart people have caught a few glimpses of the new McLaren SLR Speedster riding the track in Nordschleife, Germany. There aren’t any tech details or at least we haven’t heard anything, but it is rumored that the new car will be lighter and more powerful than the SLR and the SLR Roadster. What we know for sure is that it should top at 220mph and that it will be unveiled at the end of this month. Here’s a small gallery and some pictures of the new McLaren SLR Speedster. I like it camouflaged, too, don’t you?

Next year the McLaren SLR is not going to be produced anymore. The two companies, Mercedes and McLaren decided to split and take their own paths with their own SLR successor. Rumors say that Mercedes will name their new model, SLC, while McLaren only has a project so far, project P11.

The same rumors said that McLaren P11 will be powered from a 550bhp V8 engine built by Mahle in Northamptonshire, England, and will probably be based on the current Mercedes unit. There will also be a McLaren P12, inspired from the famous McLaren F1 supercar and should be powered by a 600 bhp V10 engine.

It will be very interesting to see the new McLaren P11 live, but not before March 2010.
